PVC Test Plug 1/2" Blue Onnline F-693358-P for Pressure and Leak Testing

Onnline PVC Test Plug 1/2" Blue (model F-693358-P) is a lightweight blue PVC sealing plug designed to provide a temporary, reliable seal for 1/2-inch openings during pressure and leak testing. Intended for use with pipelines, fittings and fixtures, the plug isolates sections of plumbing or HVAC systems for maintenance, installation checks and diagnostic procedures. Its compact form factor and plastic construction make it simple to insert and remove without tools in many routine testing tasks.

Advantages

The PVC construction offers chemical resistance to common plumbing fluids and reduced risk of corrosion compared with metal plugs. The plug’s ergonomic shape and smooth surface facilitate quick installation and removal by hand. Being lightweight and reusable, it reduces handling fatigue and supports repeated on-site testing. The distinctive blue colour improves visibility during inspections and helps identify test points.

Suitable for

• Temporary sealing of 1/2-inch pipe openings for pressure testing
• Leak detection and isolation during plumbing repairs
• Isolation of fittings and fixtures during HVAC commissioning and maintenance
• Diagnostic checks and installation validation of small-bore systems

Key specifications

• Material: polyvinyl chloride (PVC)
• Nominal connection size: 1/2 inch
• Colour: blue
• Designed application: pressure and leak testing of pipes, fittings and fixtures
• Form: removable sealing plug for temporary isolation

How to use

Select an appropriately sized opening and ensure mating pipe or fitting surfaces are clean and free of debris. Insert the plug into the 1/2-inch opening until seated, applying even hand pressure to form the temporary seal. Perform pressure or leak tests according to relevant procedures and safety guidelines. After testing, relieve any trapped pressure, then withdraw the plug by hand; inspect the plug and the sealing surfaces for wear or damage before reuse.

Usage recommendations

Use the plug only for temporary testing and isolation; do not rely on it as a permanent seal. Check compatibility with any fluids present in the system and avoid exposure to temperatures or pressures beyond the limits appropriate for PVC. Replace the plug if signs of cracking, deformation or hardened surfaces appear to maintain test accuracy and safety.
